I have this code in an os x playground (XCode Version 7.2 (7C68)):
let urlString = "https:/
let url = NSURL(string: urlString)!
let listData = NSData(contentsOfURL: url)!
var dataString = String(data: listData, encoding: NSUTF8StringEncoding)
print(dataString)
and what seems to me to be equilivent code in an OS X app I'm building:
static func httpRequest(urlString: String) -> String {
if let url = NSURL(string: urlString) {
if let urlData = NSData(contentsOfURL: url) {
return String(data: urlData, encoding: NSUTF8StringEncoding) ?? "httpRequest: string f
/
} else {
return "httpRequest: nsdata failed"
}
} else {
return "httpRequest: nsurl failed"
}
}
The "if let" constructs I added to find out what was happening. I
could use one of the several wrappers around the HTTP get/et. al.,
but I want to understand myself what's happening before I trust
other code.
In the playground the extraction from NSData works and the large
(56K?) string is printed. In the OS X app the String() fails and I
don't understand why.
Why does the String() creation in the OS X app fail?
TIA
(I'm using the "static func" construct inside a "struct" because
this is the only way I have found to create tests without error.)
(I've cross posted this to three groups total to get an answer.)
